LAMP.

Patented Jan. 27, 1914.

Application filed December 4, 1912. Serial No. 734,965.

To all r'LC/omit ntaj/ conve/n:

Be it known that I, T .TOMAS OBiunn, a i citizen ot the United States,residing at'` Brooklyn. in the county ot Kings and State. i of New York.have invented certain newI and useful Improvements in Lamps: and l i dohereby declare the following' to be a full, clear, and exact descriptionof the invention. such as will enable others skilled in the art to whichit apperta-ins to make and use the saine,

This-invention relates to lamps and stoves and more particularly tothat-type using wicks and has tor an object to provide means forexposing more or less ot' a portion ot the wick so as to-increase ordecrease the flame.

A further object of this invention is to provide a. simple devicehavingthe least number ot parts using' a. wick which does not vary itsvertical movement with respect to tht` reservoir of the lamp or stove.

.t further object of this invention is a provision ot' a removable tipwhich when charred may be thrown a l'ay to avoid the trimming of thewick.

A furthe" object of this invention is a provision of a wick whichterminates at the bottom oi the reservoir at. all times so as toabsolutely drain the reservoir.

.ft further object of this invention is the provision ot' an adjustingmeans tor exposing more or less of the wick which adjusting means servesas a support tor a globe or chimney.

A further object of this invention is the provision ot an adjustingmeans 'tor exposing more or less of the wick which ad3usting means isrotatable to vary its relation with respect to the Wick.

Further objects will be apparent from the following specification,appended claims and drawings. in Which. r

Figure i is a vertical sectional view through a lamp constructed inaccordance with this invention, Fig. 2 is a horizontal sectional view onthe. line 22 of Fig. l, and Fig. i, is a similar view'on the line 3-3 ofThis invention provides for a stationary nate at the bottom of thereservoir at all times so as to drain the entire contents ot theIreservoir and has a further provision for trimming of the wick as by aremovable tip which may he replaced when charred.

ln retaining the wick in stationary position it is necessary that. somevertically adjustabli` means be provided to expose more or lessI ot thewick so as to diminish or intens' "v the fiame.

Hotel ring' to the drawings there is shown a reservoir l0 havin;r thecentral air passage ll which terminatesl above the reservoir as shownand is provided with a perforated hood l). The top ot the reservoir isformed to provide an opening 13 which is internally threaded to receivethe externally threaded sleeve 14 which sleeve has its interior sparedfrom the air duct 1l to admit the wick 15 which terminates near the topot the air duct 1l. and at the bottom of the reservoir 1t) so that aslong as any oil remains within the reservoir, the wick exerts itsabsorbing action and conducts the oil to to t'orm a covering over theend o't'the Wick lo to prevent that portion of the wick from burning`and this hood is Jfurther provided with a depending flange 17 which fitsWithin the air duct ll. The air passages 18 through the hood aredisposed so as to directcurrents ot air within the annular llame topromote con'ilmstion and enlarge the iian'ie.

The sleeve 14 is rotatable in the threaded openingy 13 so that rotationthereof in one direction causes a downward motion of said sleeve whereasrotation in the opposite direction raises thosleeve so as to cover moreor less ot the tip 16. The sleeve is provided with a. flange 19 whichterminates in a bead t'or manipulation thereof and this fiange is alsoprovided with a series ot' erforations 20 to admit air between the g'obe 21 and the tip lf3 to support combustion.

The operation of the lamp is obvious and it is clearly seen thatrotation of the disk 14 in one direction covers the tip 16 so as toextinguish the tiame While rotation in the other direction exposes thewick so that the same may be lighted and there is an adjustnient for anyrange ot' exposure of the wick.

Modifications may be made within the scope of this invention and I donot restrict myseltl to the form'shown which is submitted forillustrative purposes only.

Having thus described my invention, I claim:

1. In a burner, a reservoir, a central duct therein, said central duetrising above the level of the reservoir, a textile sectional Wick aboutthe central duct, a sleeve carried by. 4said reservoir, said sleevehaving adjustment with said reservoir by circumferential movement, anannular flange carried by said sleeve and a eap carried by said centralduet for said duct and sectional wick.

2. In a burner, a reservoir, a central duct therein, said central ductrising above the reservoir, a stationary wick in said reservoir aboutsaid central duet., a longitudinally movable sleeve in engagement withand about said wick, said sleeve having direct threaded engagement withsaid reservoir, a Cap carried by said central duet and a removablesection o-t' textile wick superimposed on said stationary Wick,

il. In a burner for lamps or stoves, a reservoir a stationary sectionalwick about said central duet, a sleeve having threaded eonl nection withsaid reservoir and having longitudinal movement with respect thereto,said sleeve surrounding said Wick sections, a perforated flange carriedby said sleeve, a chimney carried by said flange outside of theperforations and a cap carried by said central duct said cap overhangingsaid duct to form a' shoulder over said Wick sections and said caphaving a perforated wall in4 alinement with the exterior of said Wickvsections.

4. In a burner, a movable sleeve serving as a closure for a reservoirand as a regulator for eX osing a wick, said sleeve com prising a tuular member having a smooth inner surface, a perforated flange formed onthe periphery thereof spaced from one end, a bead formed on theperiphery of said iiange, said tube having a port-ion of its length cutin screw threads, and said tube being plain for an interval between thesri-ew threads and the opposite end thereof.

In testimony whereof I aix my signature in presence of two Witnesses.

THOMAS OBRIEN.
